[Users] Add Bing Maps as baselayer

[Andreas Hocevar]

Eric,

I think your idea makes sense, and could even be made the default
behavior. In addition to your patch, we would have to make an API review
of the whole library and add the possibility to add a
GeoExt.data.LayerRecord instead of an OpenLayers.Layer everywhere we
work with layers. And the same with GeoExt.MapPanel and OpenLayers.Map.
Otherwise we may run into problems with components doing things like
accessing layer.map before the map is rendered.

Regards,
Andreas.
